Uwe,

        Same problem here.  We filed a tar with MOS and got back that it is a 
bug in the Oracle kernel & should be fixed in 11gR2.

Subject: "Long" hostnames, Oracle 9+10 and HP-UX

Dear fellows,

at my current site we got a bunch of new DB servers running under HP-UX.
The servers are configured to support host names up to 64 characters and
some of them already exceed the former 8 character limit.

After starting up an Oracle 10gR2 instance, I found in the logs and traces
that the host name was truncated to 8 characters. The same can be observed
in v$instance or sys_context('userenv','host').

So far I found only one document describing this on MOS but no further
pointers to potential problems or bugs.
https://supporthtml.oracle.com/ep/faces/secure/km/DocumentDisplay.jspx?id=957443.1

Do you have any experiences with this?
Would you recommend to switch back the hostnames to 8 characters?

Regards,
Uwe
